variant with ncursesw/ subdirectory is not available.
The patch also minimize number of HAVE_...NCURSES_H macros in

available.

The util-linux code was previously aligned to use @localstatedir@ and
the util-linux build system was set to override the default to use /run.
Current GNU Coding Standards introduced the @runstatedir@ variable
for this purpose. Lets use that instead.
The GNU default for @runstatedir@ is ${localstatedir}/run so util-linux
still override the default to be /run to preserve the status quo from
before. The only difference is that you'll now pass --runstatedir to
override the location on the command line instead of --localstatedir.
(FWIW, Debhelper in compat 11 will automatically start passing
--runstatedir=/run to all autotools configured builds. It already
passes --localstatedir=/var (to avoid it ending up with the GNU default
/usr/local/var) which breaks the util-linux build system code that
tries to default it to /run. This change will thus allow util-linux
and debhelper to work better together and avoid the need for a
package-specific override.)

It seems Debina 8 is a little bit incompatible with us:
* ncurses-config is packaged in ncurses-bin where is *no* any
development files! It means the script returns paths to not installed
files (IMHO packaging bug)
Fixed, we need to check for header files too.
* term.h is "everywhere" on Fedora:
<term.h>
<ncurses/term.h>
<ncursesw/term.h>
Debian is more strict and uses <ncurses[w]/term.h> only.
Fixed, we need #ifdef storm to use the correct path
* libtinfo-dev does not contains any header files
Fixed, we have to always require installed ncurses devel stuff to compile,
but we can link with -ltinfo only (cal, ul, more, ...)

System call getrandom(2) is relatively new, available since kernel 3.17 but
not supported by glibc 2.24. That in mind autotools is made to check
availability of this function and keep old code as fallback. It is
reasonable assume it will take years before the syscall(2) and fallback are
unproblematic to remove.
One might ask why bother using getrandom(2). Main reason is to avoid
unnecessary system calls to achieve exactly same end result. That
demonstrated with 'strace -c ./mcookie' showing 36 calls before, and 32
after this change. Secondly the getrandom(2) function got to kernel with
promise it can be used to avoid file descriptor run down, and since uuidd
uses random_get_bytes() it should fulfill it's promise here.

Let's hope this is last change necessary to cleanup x-* usage:
x-* persistent option, stored in utab, available for umount, etc.
X-* fstab comment only
mount(8) supports x-mount.mkdir= as well as newly recommended X-mount.mkdir=
Advantages:
* less invasive
* does not require exception for x-systemd
* does not require rename x-initrd to X-initrd
The systemd and dracut users will get the new (=fixed) functionality without a
change in fstab configuration. This is the primary goal.
Disadvantages:
* not 100% compatible libmount behavior, x-* options have not been
previously stored in utab. The API is the same, options will be still
available, but on x-* libmount will write to /run/mount/utab. For now
it seems only systemd uses x-*, and they like this behavior, so...

The previous patch introduces X-* options namespace for options
that have to be maintained in user space.
Unfortunately, systemd users already use mount options that are
necessary by umount or another operations. The conclusion from
discussion with systemd guys is to store all the systemd options
in userspace.
It seems better to add one line exception to libmount than force all
fstab users to rename x-systemd to X-systemd.

last(1) and utmpdump(1) does not use them, see below.
utmpx.h is used in:

utmpxname -> login agetty write lslogins
updwtmpx -> login agetty runuser su
